16/8-voice analog sound

(prologue-16)

The prologue is a polyphonic analog synthesizer with 8 or 16
multitimbral voices. KORG’s analog synthesizer development in recent years has
culminated in the prologue, which was designed using 11,000 discrete electronic
components. Although the prologue is a flagship instrument, it still retains
the inviting feel and accessibility of its predecessors. It features a pure
analog path, impeccable sound quality, stunning presence unlike any other poly
synth, and the same intuitive interface as the minilogue and monologue,
granting you intuitive access to a vast world of analog synthesis.

The prologue uses a structure of 2VCO + MULTI ENGINE, 1VCF, 2EG, 1VCA, and
1LFO. In addition to distinctive, original circuitry, such as wave shaping to
shape the oscillator’s overtones and a sync/ring switch, prologue also features
a two-pole low pass filter with enhanced sharpness, drive that adds powerful
distortion, and a low cut (high pass) switch. Every detail has been improved on
from minilogue and monologue. Its sound covers every sonic possibility: fat
basses, powerful leads, and the beautiful pads that you expect from a
polyphonic synthesizer.

Newly developed multi-engine

The ingenuity of prologue goes beyond its analog design. The
newly developed multi engine is provided as VCO3, adding digital waveforms and
FM. This multi engine, which is equipped with three different sound engines,
can be combined with the analog VCOs to expand prologue’s sonic potential far
beyond that of a traditional analog synthesizer.

Noise generator

There are four types of noise generator, indispensable for
percussive sounds or sound effects. Experience how digital filtering can
produce direct changes in the color of the noise.

VPM oscillator

The VPM (Variable Phase Modulation) / FM oscillator was
newly developed for prologue. Its metallic and sharp sounds with their complex
overtones could never be obtained by analog means. With 16 types of oscillator
and the SHAPE knob, you’ll be intuitively guided through complex sound design.
Combine these wave shapes with prologue’s gorgeous analog filters, and prepare
for sounds you never thought possible.

User oscillator

The user oscillator section lets you load oscillator
programs of your own creation. Sixteen slots are provided, and one type of
morphing wavetable oscillator is built-in as a preset.

Digital effects

The high-quality digital effects feature pristine 32-bit
floating-point processing, and add a further polish to the sound of the
prologue. With two effect units provided (a modulation effect and
delay/reverb), you can choose from a wide variety such as chorus or ensemble,
warm tape delay, or diverse reverbs. The user effect slots let you load effect
programs of your own creation.

User-customization

Prologue-8

The prologue offers an SDK (Software Development Kit) that
allows developers to program, customize and extend the capabilities of the
multi-engine and digital effects. The prologue provides 16 user oscillator
slots and 16 user effect slots, and users can use the prologue Librarian
software to load into their prologue new oscillators and effect programs
created by developers with the prologue SDK (Software Development Kit).

What types of sound will you create by combining the expanded digital
oscillators with analog synthesis? You can create original programs and share
code to participate in the user community. Start with sample code provided by
KORG. The prologue belongs to you.

Analog comp/booster

The exclusive VU meter is available only on the prologue-16,
and indicates the newly developed master effect L.F. COMP. It’s a low end
booster/compressor using an analog circuit, delivering a solid sense of
presence that cannot be obtained from a simple EQ. You’ll particularly notice
the difference in high-volume stage performances where maximum dynamics can be
utilized.

prologue-16

Bi-timbral

(prologue-16)

The prologue is a two-timbre synthesizer that lets you play
two different programs simultaneously. In addition to layer and split, you can
use crossfade to smoothly transition between the main timbre and sub timbre. An
ample 16 or 8 voices ensure that the player’s advanced performance needs will
be met.

Voice modes

The prologue provides voice modes that let you freely
combine the 16 or 8 voices for performance. The standard POLY mode lets you
play chords with up to 16 or 8-note polyphony. MONO mode is ideal for bass
using the sub-oscillator. UNISON allows you to generate thick lead tones by
sounding all voices in unison. CHORD lets you play chords with one finger. In
conjunction with the DEPTH knob, you can use these modes to obtain a variety of
effects.

Four voice modes

- POLY: Operates as a poly synth with up to 16 or 8
voices. Turn the VOICE MODE DEPTH knob to switch to DUO mode, in which the
instrument operates in unison as a poly synth with up to 8 or 4 voices. - MONO: Operates as a mono synth with sub oscillator. - UNISON: Operates as an all-unison mono synth. - CHORD: Plays chords.

Arpeggiator

The powerful arpeggiator opens up a world of limitless
inspiration. It provides a four-octave range, and six arpeggiator types
including manual set. From phrases that could not be performed on a keyboard to
sequence-like sound designs, the arpeggiator can play a versatile array of
roles.

Program sort

The program sort function lets you instantly change the
sorting order of the 500 programs. You can sort by category, alphabetical
order, use LIKE to view the programs that you marked as your favorites,
FREQUENT to sort the programs in order of their frequency of use, or ENVELOPE
to sort the programs in order of their envelope shape (note duration). By
choosing from eight different sorting conditions, you’ll be able to quickly
find the sound that you need, without interrupting the tempo of your rehearsal
or production workflow.

Eight program sort methods

- PROG NUM: Sort by program number. - CATEGORY: Sort by program category. - ALPHABETICAL: Sort programs alphabetically. - LIKE: Sort by programs that you "liked." - FREQUENT: Sort by how frequently you used the program. - ENVELOPE: Sort by envelope shape. - RANDOM: Sort randomly. - LIVE SET: Sort programs registered in a live set.

Japanese-made natural touch keyboard

prologue-16

The attention to detail expected of a flagship extends to
prologue’s playability and design as well.

The keyboard is a high-quality Japanese-made natural touch keyboard, providing
the same superb touch and feel as on KORG’s high-end workstations, and allowing
a high degree of expressive power.

prologue’s body emanates beauty and the presence of a boutique synth, and newly
redefines the look of a classic synthesizer. The black aluminum front panel
features the same curvature as the minilogue, and sports a beautiful hairline
finish. Metal knobs with a sense of weight, diamond-cut silver indices, and oak
wood side panels are some of the details that emphasize the high quality of
this Made In Japan instrument.

Each program provides a program sort function that includes
voice mode and timbre settings, and allows up to 8 × 4 banks of live set
programs to be registered. Voice Mode 4 (POLY, MONO, UNISON, CHORD).

The VOICE MODE DEPTH setting allows different parameters to
be varied for each mode. Timbres Max two timbre (Main timbre, Sub timbre)
